DETAILED DESCRIPTION

Example methods and systems are directed to selecting users relevant to attributes of a geofence. Examples merely typify possible variations. Unless explicitly stated otherwise, components and functions are optional and may be combined or subdivided, and operations may vary in sequence or be combined or subdivided. In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of example embodiments. It will be evident to one skilled in the art, however, that the present subject matter may be practiced without these specific details.

A system may be used to provide geofence data for a geofence that is determined to be relevant to a user. The system may determine that the geofence is relevant to the user by matching attributes of the geofence to the preferences of the user. Once a user has been identified to be relevant to the geofence, the system may send the geofence data to the mobile device belonging to the user. The geofence data may be used by the mobile device to detect that the user crosses the geofence. Thereafter, notifications may be presented to the mobile device of the user. Moreover, the resulting notifications may present information that is relevant to the user. Alternatively, crossing the geofence may trigger an option to be performed by the mobile device of the user. The operation may include displaying the notifications on the mobile device of the user. The notifications may be included as part of the geofence data that is sent from the system to the mobile device.

FIG. 1 is a network diagram illustrating a network environment 100 suitable for selecting users relevant to attributes of a geofence, according to some example embodiments. The network environment 100 includes a geofencing machine 110, a database 115, and devices 130, and 150, all communicatively coupled to each other via a network 190.

Also shown in FIG. 1 is user 132. User 132 may be a human user (e.g., a human being), a machine user (e.g., a computer configured by a software program to interact with the device 130), or any suitable combination thereof (e.g., a human assisted by a machine or a machine supervised by a human). The user 132 is not part of the network environment 100, but is associated with the device 130 and may be a user of the device 130. For example, the device 130 may be a desktop computer, a vehicle computer, a tablet computer, a navigational device, a portable media device, or a smart phone belonging to the user 132.

Also included in FIG. 1 is a geofence 175 that is surrounding a retail store 170. The geofence 175 may include attributes that represent characteristics of the retail store 170 such as hours of operation of the retail store 170, location of the retail store 170, merchandise items available for sale from the retail store 170, or any suitable combination thereof. The geofencing machine 110 may also receive preferences of the user 132 from the device 130 operated by the user 132. The geofencing machine 110 may determine that the user 132 has preferences that match with the attributes of the geofence 175. As a result, the system may send geofence data to the device 130 operated by the user 132, the geofence data being representative of the geofence 175 or a series of geofences including geofence 175. Thereafter, the geofence data on the device 130 may be used to detect when the user 132 crosses into the geofence 175 or is within the geofence 175. As a result, the geofencing machine may present a notification to the device 130 of the user 132 detected as being within the geofence 175. Moreover, the notification may pertain to merchandise items from the retail store 170. In some examples, when a user, such as user 132, crossing into a geofence, such as geofence 175, an application running on the device 130 may trigger some operation to be performed by the device 130. The operation may include the device 130 displaying the notification which pertains to the merchandise items.

Any of the machines, databases, or devices shown in FIG. 1 may be implemented in a general-purpose computer modified (e.g., configured or programmed) by software to be a special-purpose computer to perform one or more of the functions described herein for that machine, database, or device. For example, a computer system able to implement any one or more of the methodologies described herein is discussed below with respect to FIG. 8. As used herein, a “database” is a data storage resource and may store data structured as a text file, a table, a spreadsheet, a relational database (e.g., an object-relational database), a triple store, a hierarchical data store, or any suitable combination thereof. Moreover, any two or more of the machines, databases, or devices illustrated in FIG. 1 may be combined into a single machine, and the functions described herein for any single machine, database, or device may be subdivided among multiple machines, databases, or devices.

The network 190 may be any network that enables communication between or among machines, databases, and devices (e.g., the geofencing machine 110 and the device 130). Accordingly, the network 190 may be a wired network, a wireless network (e.g., a mobile or cellular network), or any suitable combination thereof. The network 190 may include one or more portions that constitute a private network, a public network (e.g., the Internet), or any suitable combination thereof. Accordingly, the network 190 may include one or more portions that incorporate a local area network (LAN), a wide area network (WAN), the Internet, a mobile telephone network (e.g., a cellular network), a wired telephone network (e.g., a plain old telephone system (POTS) network), a wireless data network (e.g., WiFi network or WiMax network), or any suitable combination thereof. Any one or more portions of the network 190 may communicate information via a transmission medium. As used herein, “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding, or carrying instructions for execution by a machine, and includes digital or analog communication signals or other intangible media to facilitate communication of such software.

FIG. 2 is a block diagram illustrating components of the geofencing machine 110, according to some example embodiments. The geofencing machine 110 is shown as including an identification module 210, a selection module 220, a communication module 230, a detection module 240, and a presentation module 250, all configured to communicate with each other (e.g., via a bus, shared memory, or a switch). Any one or more of the modules described herein may be implemented using hardware (e.g., a processor of a machine) or a combination of hardware and software. For example, any module described herein may configure a processor to perform the operations described herein for that module. Moreover, any two or more of these modules may be combined into a single module, and the functions described herein for a single module may be subdivided among multiple modules. Furthermore, according to various example embodiments, modules described herein as being implemented within a single machine, database, or device may be distributed across multiple machines, databases, or devices.

In various example embodiments, the identification module 210 is configured to identify attributes of a geofence surrounding a location. The attributes of the geofence may represent merchant characteristics of a brick-and-mortar store (e.g., a physical retail location where items may be purchased from a merchant) located within the geofence or another physical location. For example, merchant characteristics may include hours of operation for the brick-and-mortar store, a target demographic served by the brick-and-mortar store, location of the brick-and-mortar store, or any suitable combination thereof. Merchant characteristics may also indicate a season during which the brick-and-mortar store most active (e.g., a season of the year during which the brick-and-mortar store is most frequently visited by customers). Merchant characteristics may also indicate aesthetic characteristics of the brick-and-mortar store (e.g., layout, culture, feel). In various example embodiments, the attributes of the geofence may also represent item characteristics of merchandise items available for sale from the brick-and-mortar store. The item characteristics may indicate at least one of a category of the merchandise items, price range of the merchandise items, purpose served by the merchandise items, features of the merchandise items, a targeted demographic for users of the merchandise items, or any suitable combination thereof. Item characteristics may also indicate whether the item is common, luxurious, or any suitable combination thereof. In various example embodiments, the attributes of the geofence may indicate times during which the geofence is active. In some instances, the times during which the geofence is active may correspond to hours of operation of the brick-and-mortar store surrounded by the geofence. In various example embodiments, the attributes of the geofence may also indicate software compatibility of the merchandise items available for sale from the brick-and-mortar store. For instance, the merchandise items inside the brick-and-mortar store may be software applications that are compatible with Android devices. As another example, the merchandise items inside the brick-and-mortar store may be software applications that are compatible with iOS devices.

In various example embodiments, the selection module 220 is configured to select a subset of users from a plurality of users eligible to receive the geofence based at least in part on matching the attributes of the geofence to preferences associated with each user among the subset of users. The preferences associated with each user may indicate item preferences, location preferences, time preferences, or any suitable combination thereof. For instance, the item preferences of the user may indicate item characteristics that the user prefers or item characteristics of items having the greatest likelihood of being purchased by the user. Location preferences may indicate areas frequently visited by the user or locations having a greatest likelihood of being visited by the user. Time preferences may indicate hours during which the user is most likely to be engaging in shopping activity. In various example embodiments, the plurality of eligible users may be determined by the selection module 220 as users that have a mobile application installed on their client devices. The mobile application may be capable of receiving geofence data from the geofencing machine 110. The selection module 220 may be further configured to determine that the selected subset of users have preferences that match with at least a threshold number of the attributes of the geofence. In various example embodiments, the selection module 220 is further configured to select the subset of users eligible to receive the geofence based on matching the attributes of the geofence to user demographics of the plurality of users. The user demographics of the plurality of users may be retrieved by the communication module 230, as further explained below. The user demographics may indicate at least one of gender, race, occupation, dietary preferences, age, marital status of each of the plurality of users, or any suitable combination thereof. In various example embodiments, the selection module 220 is further configured to select the subset of users based in part on determining that the subset of users are located within a pre-defined distance from the geofence. The communication module 230 may be configured to receive location data from each of the client devices operated by the plurality of users. Moreover, the location data may be used to indicate a location of the user (e.g., location coordinates, address). The location data can be collected by a mobile application installed on each of the client devices. Moreover, the subset of users may authorize the collection of the location data by the mobile application. The selection module 220 may be further configured to determine that users included in the subset of users are located within the pre-defined distance from the geofence based on the received location data. In various example embodiments, the selection module 220 is further configured to perform the selection of the subset of users during the active times indicated by the attributes of the geofence. For instance, the selection module 220 may perform selection of the user during the hours of operation of the brick-and-mortar store located within the geofence. As another example, the selection module 220 may perform selection of the user during the season when the brick-and-mortar store is most active (e.g., a season of the year during which the brick-and-mortar store is most frequented visited by customers). For example, during Christmas time, the brick-and-mortar store may have the greatest amount of customers and the selection module 220 may perform selection of the subset of users during that season. In various example embodiments, the selection module 220 is further configured to select the subset of users based in part on the software compatibility of the merchandise items available for sale. For instance, the selection module 220 may select users that are operating devices compatible with Android software because the brick-and-mortar store has software applications for Android. In various example embodiments, the selection module 220 may further determine that the users excluded from the subset of users have preferences that match with less than a pre-defined threshold amount of the attributes of the geofence. For instance, users that prefer to shop for shoes may be excluded from a geofence surrounding a brick-and-mortar store that sells cosmetics. As another example, users that prefer to shop in the evenings may be excluded from a geofence surrounding a brick-and-mortar store that is open only in the mornings.

In various example embodiments, the communication module 230 is configured to send geofence data representing the geofence to each of the client devices operated by the subset of the plurality of users in order to detect users of the client devices that cross the geofence surrounding the location. The geofence data may be representative of the geofence. For instance, the geofence data may be location coordinates that indicate the boundaries of the geofence. As further explained below, the geofence data may be used to detect when a user crosses the geofence. Each user among the plurality of users may be operating a client device in communication with a central server. Moreover, the communication module 230 may be used to facilitate the communication between each of the client devices with the central server. The preferences of the plurality of users may be retrieved by the central server based at least in part on the communication with the central server. In various example embodiments, the communication module 230 may retrieve the preferences of the plurality of users from a database managed by the central server. The database may include profiles corresponding to the plurality of users. In various example embodiments, the communication module 230 may retrieve the preferences of the plurality of users from each of the client devices operated by the plurality of users. In various example embodiments, the communication module 230 is further configured to retrieve user demographics of the plurality of users based at least in part on the communication between the client devices with the central server, such as via a mobile application installed and authorized by the user.

In various example embodiments, the detection module 240 is configured to receive an indication, from a client device operated by a user among the plurality of users, of the user crossing into the geofence based on the geofence data sent to the client device operated by the user. In various example embodiments, the detection module 240 is further configured to track user activity across each of the client devices and storing information related to the user activity in the profiles corresponding to the plurality of users. In various example embodiments, the detection module 240 may be further configured to receive the user activity from each of the client devices. In other words, the user activity information may be sent at regular intervals to the detection module 240 by the client device. The profiles corresponding to the plurality of users may be stored in the database managed by the central server. The user activity may be used to indicate the preferences of each user among the plurality of users. As stated previously, the preferences associated with each user may indicate item preferences, location preferences, time preferences, or any suitable combination thereof. For instance, the detection module 240 may receive purchase history information that may indicate items previously purchased by each user. The purchase history information may further indicate a price range of the items previously purchased by each user. As another example, the detection module 240 may receive time information that may indicate hours during which each user is engaging in purchasing behavior. Lastly, the detection module 240 may receive travel information that indicates stores previously visited by each user. The user activity information may include information collected as the user performing actions on the client device using a mobile application installed on the client device.

In various example embodiments, the presentation module 250 is configured to present a notification to the client device operated by the user in response to the detection module 240 detecting the user as crossing into the geofence. The notification may regard the merchandise items available for sale from the brick-and-mortar store. The notification may be displayed by a mobile application installed on the client device. For instance, the mobile device may receive the notification in the form of data which is then processed by an application or an operating system installed on the mobile device for display. In various example embodiments, the presentation module 250 may present the notification to the client device in order to trigger performance of a pre-defined function on the client device. The pre-defined function may include displaying the notification.

In various example embodiments, device 130 of FIG. 1 may be represented by the mobile device 300 of FIG. 3. The mobile device 300 may include a processor 310. The processor 310 may be any of a variety of different types of commercially available processors suitable for mobile devices (for example, an XScale architecture microprocessor, a Microprocessor without Interlocked Pipeline Stages (MIPS) architecture processor, or another type of processor). A memory 320, such as a Random Access Memory (RAM), a Flash memory, or other type of memory, is typically accessible to the processor. The memory 320 may be adapted to store an operating system (OS) 330, as well as application programs 340, such as a mobile location enabled application that may provide LBSs to a user. The processor 310 may be coupled, either directly or via appropriate intermediary hardware, to a display 350 and to one or more input/output (I/O) devices 360, such as a keypad, a touch panel sensor, a microphone, and the like. Similarly, in some embodiments, the processor 310 may be coupled to a transceiver 370 that interfaces with an antenna 390. The transceiver 370 may be configured to both transmit and receive cellular network signals, wireless data signals, or other types of signals via the antenna 390, depending on the nature of the mobile device 300. In this manner, the connection with network-based system 105 via the network 190 may be established. Moreover, user activity on the mobile device 300 may be transmitted via the transceiver 370 from the mobile device 300 to the geofencing machine 110. Further, in some configurations, a GPS receiver 380 may also make use of the antenna 390 to receive GPS signals. The GPS signals may be used to track the location of the mobile device 300. Moreover, the GPS signals may constitute location data which may be transmitted from the mobile device 300 to the geofencing machine 110.

FIG. 4 is an example user interface of a notification 400 displayed on a client device operated by a user, according to some example embodiments. The notification 400 may be presented by the presentation module 250 in response to the detection module 240 detecting that the user crosses into a geofence. Moreover, the user may have been selected by the selection module 220 as having preferences that match with the attributes of the geofence. The notification 400 may include a description 402 of how the geofence relates to the user (e.g., user has expressed an interest in shoes). Moreover, the notification 400 may indicate that there are two stores located within the geofence that carry shoes. The notification 400 may also include a further description 404 of how the geofence relates to the user (e.g., user has expressed an interest in fiction books). Moreover, the notification 400 may indicate that there is a book store located within the geofence that carries fiction books.

FIG. 5 is an example user interface of a notification 500 displayed on a client device operated by a user, according to some example embodiments. The notification may be presented in response to the user clicking on the option 404 in FIG. 4. The notification 500 may display shoe store 502 and shoe store 504 as both being located within the geofence. Moreover, the notification 500 may further display hours of operation for the shoe store 502 and for the shoe store 504. In various example embodiments, the hours of operation for the shoe store 502 and for the shoes store 504 may be represented as attributes of the geofence. Moreover, the location of each of the shoe stores 502 and 504 may be represented as attributes of the geofence. Lastly, the user may be selected by the selection module 220 as having preferences that match with the attributes of the geofence. For instance, both the shoe stores 502 and 504 may be open during the hours when the user prefers to go shopping. Moreover, both shoe stores 502 and 504 may be location within a pre-defined distance from the location of the user. The notification 500 may also display information regarding merchandise items available from each of the stores 502 and 504. For instance, a message 506 regarding running shoes available from store 502 may be displayed. Moreover, a message 508 regarding tennis shoes available from store 504 may be displayed.

Examples of such input components 830 include an image input component (e.g., one or more cameras), an audio input component (e.g., a microphone), a direction input component (e.g., a compass), a location input component (e.g., a global positioning system (GPS) receiver), an orientation component (e.g., a gyroscope), a motion detection component (e.g., one or more accelerometers), an altitude detection component (e.g., an altimeter), and a gas detection component (e.g., a gas sensor). Inputs harvested by any one or more of these input components may be accessible and available for use by any of modules described herein.

As used herein, the term “memory” refers to a machine-readable medium able to store data temporarily or permanently and may be taken to include, but not be limited to, random-access memory (RAM), read-only memory (ROM), buffer memory, flash memory, and cache memory. While the machine-readable medium 822 is shown in an example embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store instructions. The term “machine-readable medium” shall also be taken to include any medium, or combination of multiple media, that is capable of storing the instructions 824 for execution by the machine 800, such that the instructions 824, when executed by one or more processors of the machine 800 (e.g., processor 802), cause the machine 800 to perform any one or more of the methodologies described herein, in whole or in part. Accordingly, a “machine-readable medium” refers to a single storage apparatus or device, as well as cloud-based storage systems or storage networks that include multiple storage apparatus or devices. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, one or more tangible data repositories in the form of a solid-state memory, an optical medium, a magnetic medium, or any suitable combination thereof.

Throughout this specification, plural instances may implement components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently or in other orders. Accordingly, the illustrated order is not intended to be limiting. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components. These and other variations, modifications, additions, and improvements fall within the scope of the subject matter herein.

Certain embodiments are described herein as including logic or a number of components, modules, or mechanisms. Modules may constitute either software modules (e.g., code embodied on a machine-readable medium or in a transmission signal) or hardware modules. A “hardware module” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein.

In some embodiments, a hardware module may be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware module may include dedicated circuitry or logic that is permanently configured to perform certain operations. For example, a hardware module may be a special-purpose processor, such as a field programmable gate array (FPGA) or an ASIC. A hardware module may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware module may include software encompassed within a general-purpose processor or other programmable processor. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.

Accordingly, the phrase “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. As used herein, “hardware-implemented module” refers to a hardware module. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where a hardware module comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware modules) at different times. Software may accordingly configure a processor, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.

Hardware modules can provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).

The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented module” refers to a hardware module implemented using one or more processors.

Similarly, the methods described herein may be at least partially processor-implemented, a processor being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented modules. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an application program interface (API)).

The performance of certain operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the one or more processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the one or more processors or processor-implemented modules may be distributed across a number of geographic locations.

Some portions of the subject matter discussed herein may be presented in terms of algorithms or symbolic representations of operations on data stored as bits or binary digital signals within a machine memory (e.g., a computer memory). Such algorithms or symbolic representations are examples of techniques used by those of ordinary skill in the data processing arts to convey the substance of their work to others skilled in the art. As used herein, an “algorithm” is a self-consistent sequence of operations or similar processing leading to a desired result. In this context, algorithms and operations involve physical manipulation of physical quantities. Typically, but not necessarily, such quantities may take the form of electrical, magnetic, or optical signals capable of being stored, accessed, transferred, combined, compared, or otherwise manipulated by a machine. It is convenient at times, principally for reasons of common usage, to refer to such signals using words such as “data,” “content,” “bits,” “values,” “elements,” “symbols,” “characters,” “terms,” “numbers,” “numerals,” or the like. These words, however, are merely convenient labels and are to be associated with appropriate physical quantities.

Unless specifically stated otherwise, discussions herein using words such as “processing,” “computing,” “calculating,” “determining,” “presenting,” “displaying,” or the like may refer to actions or processes of a machine (e.g., a computer) that manipulates or transforms data represented as physical (e.g., electronic, magnetic, or optical) quantities within one or more memories (e.g., volatile memory, non-volatile memory, or any suitable combination thereof), registers, or other machine components that receive, store, transmit, or display information. Furthermore, unless specifically stated otherwise, the terms “a” or “an” are herein used, as is common in patent documents, to include one or more than one instance. Finally, as used herein, the conjunction “or” refers to a non-exclusive “or,” unless specifically stated otherwise.
